This invention. pertainsto a lighting device or starting burner for liquid fuel stoves oft-he retort class, the same, though not so limited, being especially designed for use with stoves of the type shown in applications Serial Nos. 126,366 and-149,853, filed jointly by Lee S.

Chadwick and myself onAugust 2, 1926, and 1 November 19, 1926, respectively. 7

' Ainongthe objectslof the invention are the productionof a device of the above mentioned character that'is very efficient; that is safe and reliable; that issimple and easy of operation; that isquickly responsive to the application of'a lighted match orother igniter;

that burns quietly 'withfa clean, bluefiame," v

stove top. Rising from about the longitudiavoiding the roaring noise common to prevailing burners of this class; that isrelatlvely simple of construction and economical of manufacture ;that 1s compact and that s not liableto get out of order nor become clogged with sediment, scale or carbon, "or with boiled Over foodstuff, though capable of being easily opened. or disassembled for the purpose of cleaning should such become necessary.

Secured lin about the plane of the burner pane is a unitll8 that'is in the form of a substantial to the outer side of the endpanel casting and to which is adapted to be removably attached a: fuel reservoir 19. Rising" from the innerend of the conduit '18 is a fuel pipe .or conduit 20that includes a valve 21 and connects at its upper endwith a tubular' retort 22 thatis prO ected-thrOugh an I burner 10 andhas its inner end projected 15. This retort is detailed in an application filed jointly by Lee S. Chadwick and myself on December 6, .1926, Serial No. 152,798; The valve at the .inner end of the retort is controlled by a hand wheel- 23 that-is. ;ap

aperture in the end panel 1 and across the plied to the out e'r endofthe valve stemi2 l.

In the type ofstove hereinshown', the fuel. is fed by air-pressure from the reservoir 19, through the fuel conduit 20 when the valve 21 is opentothe retort 22 where, under normal operating conditions, it is vaporized by I the heat from the burner 10. b With the'valve of the retort open, the vapor issues from the r v retortintothemixer 15: where it mixes with V i' 'airientering'throughthe downturned end of the mixer and passes on therewith to the 11 .51; ifold Gthrough which it is distributed to the burners and 11 passage of gas to the latter burner being controlled by a valve whose operating handle is shown at 25.

It may be explained that air is supplied to the reservoir 19 by means of a suit-able pump. This is in accordance with common practice and therefore illustration deemed unneces sary. So far as the pres t invention is concerned, the fuel system c l he of the grav ity feed type.

Tally improved lighting device or starting rner is designated generally oy the mun l is located adjacent the end wall it Lie mixer directly beneath the adjoincnd of the retort 22. The burner is pref erably composed of two mating sections 31 and 32, which maybe cast, the section 32 beo; substantially a counterpart of the portion or the section 31 against which it is engaged. The section is secu ed to sec ion by a screw and it is prope ositioned with respect to the section 31 b id screw and a dowel pin 34% that extend through registering holes in the two sections and enters an aperture in the end wall-16 of the mixer, Slots 35 are sawed milled, or otherwise formed in a substantially horizontal portion 36 of the burner body directly beneath the retort 22, and the adjacent end wal of the section 31 is cut away to provide a narrow vertical slot 37 when the two sections are fitted together. A deflector 38 is disposed opposite the slot 37 and he same is prefer- ;oly' formed integral with the sections 31 ant; 3;

The burner body encloses a chamber 10 including a goose neck portion 11 vents any boiled over food or other foreign" matter that drops upon the burnerfrom entering said inlet.

A bracket extends forwardly from and is preferably formed integral with the section 31, and near the previously mentioned deflector 38 has an aperture through which a screw 16 is engaged which serves to secure the burner to the end wall 16 of the mixing chamber 15. The above mentioned dowel in assists the screw 16 in properly locatig the burner with respect to said end wall. hastened, as by screws 47, to'the for vard end of thebracket 25 is a valve casing having a bore 51 that is joined by a passageway 52 in a depending branch of said casing. Connected by suitable joints to the lower end of the'branch 53, and to a lateral branch 5% of the fuel conduit 20 are the opposite ends of a tube 55, the branch 5d of the conduit being extended through an opening 56 V n in the endpanel 1. r uel is delivered through.

the tube to the valve casing 50 when the valve 21 in the fuel conduit 20 is opened. inwardly beyond its point of communication with the passageway 52, the bore 51 is re duced in diameter and threaded for cooperation with the threaded portion 58 of a valve stem 59 whose inner end is formed to edect a valve 59 that is arranged to cooperate with a seat 60 surrounding the inner end of a furt ier reduced portion 61 of the bore. i'ldapted to be secured by a union 62 to the threaded rear end63 of the valve casing is the forward end of a tubular generator 6a that has a cap 65 applied to its end remote from said union 52, said cap having a relatively small orifice 67. Extending from the inner end of the stem 59, through the generator 6d, isa rod 68 that is slightly less in diameter than the internal diameter of the snerator and a fine wire 69 protrudes from end of the rod 68 through the orifice 6?. threaded portion 68 of the stem 59 has ngitudinal groove 70, indicated by dotted in Fig. 6 throughwhich fuel may pass he enlarged portion of the bore 51 to its escape is controlled by the valve 59.

l ltted about the stem 59 and occupying the outer counterbored end of the bore 51 is a packing gland comprisedof an annulus 71 a body 72 of packing materiahand a follower 73"that is urged inwardly by a cap 75 that is movement of the stem 59, a stop 77 in the form of a split ring is contracted within a circumferential groove 7 8 that is formed adjacent the outer end of the threaded portion 58*0'1 the stem and is designed for engagement with the annulus 71.

Assuming that the reservoir 19 is supplied with fuel and that'air pressure prevails therein, the valve 21 may be opened to permit fuel topass to the generator 22 and to the valve casing 50; A lighted match or other igniting means may now beheld beneath the generator 6 1 of the starting burner and the Valve of said starting burner opened by turning the handle 7 6 in a directionto retractthe stein This will allow the fuel to pass through the generator 64 in a thin film between the wall of said generator and the rod 68 and be vaporized, in which condition it will discharge through the, orifice 6C int-o the goose neel: portion 11 of the mixing chamber 40 where it will mil: with air entering through the opening 43' and passage 12. The mixture will then t reduced inner end of the bore from which add ' nited by mentarily be discharged from the generator into the mixing chamber 40, it will flow down the inclined bottom wall of said chamber and through the slot 37 where it will be ignited and the resulting flame will assist-in heating the generator 64. The defiector38 directs the flame of the liquid fuel or gas issuing from the slot 37 upwardly against the generator.

As soon as the retort 22 is heated sufliciently to vaporize the liquid fuel therein, its valve may be opened bymeans ofthe operating handle 23 thereby to discharge the vapor from said retort into the mixer 15 from where it passes through the manifold 6 to the burner 10 and is ignited by the flame of the starting burner 30. lhe starting burner may now be turned off and the'stove will continue to operate in the usual manner.

By constructing the burner of mating halves or sections that meetv in a straight plane, the casting and the machining of the;

device are greatly facilitated and cheapened.

1 After the sections are cast it is only necessary to grind their engaging surfaces, saw; or

otherwise out the slots 35, and bore the'holes for the screwsand dowel pin, the holes in the section 31 that receive the screws 33and 47 being tapped or threaded.

7 Also, by virtue of this same feature, the burner may be very'easily cleaned in case it 7 becomes clogged from any cause, as byjforto remove the one screw 33 and withdraw the sign matter, such as boiled over food,'falling upon the burner and entering the slots 35. To clean the burner it is only necessary section 32from the dowel pin 34L, whenjall passages are readily accessible.
